Embodiment Construction

[0043] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0044] The inventors of the present invention have found that the traditional X-band transmitting components have simple existence monitoring functions and low task reliability. In a traditional X-band transmitting component, it generally includes: a transmitting channel, a control circuit and a power supply circuit, wherein the transmitting channel includes: an isolator, a driving amplifier and a power amplifier. The inventors of the present invention found that on the basis of the original launch components, adding backu...

Abstract

The invention discloses a transmitting component, wherein the transmitting component is an X-waveband transmitting component adopting a transmitting channel backup technology and adopts a pulse working mode; the working state of the transmitting component is divided into a main transmitting channel working state and a backup transmitting channel working state; the default working state is the maintransmitting channel working state; when the main transmitting channel works abnormally, the system automatically switches to the backup transmitting channel working state; two paths of peak power signal output of 33 dBm are realized by adopting the X-waveband transmitting component of the transmitting channel backup technology, the power gain is 23 dB, the secondary harmonic suppression is larger than 45 dBc, and the stray is smaller than -70dBc. The transmitting component disclosed by the invention solves the problems that the existing X-waveband transmitting component is simple in monitoring function and relatively low in task reliability; and the transmitting component is mainly applied to the condition that the reliability requirement of the working task of the system is high.

Description

technical field [0001] The invention relates to the field of radar applications. More specifically, it relates to a transmitting component, especially an X-band transmitting component using a transmission channel backup technology. Background technique [0002] The transmitting component is an important part of the X-band active phased array radar system. Its main function is to generate the transmission driving power signal of the antenna array, which requires very high reliability of the transmitting channel. The traditional X-band transmitting components include: transmitting channels, control circuits and power circuits, wherein the transmitting channels include: isolators, drive amplifiers and power amplifiers. Traditional X-band transmitting components have the disadvantages of simple monitoring function and low mission reliability. [0003] In view of the above-mentioned problems existing in the prior art, the present invention is proposed. Contents of the inventi...
